AUXILIARY SIGNAL DEVICE.

To all 'whom it may concern:

Be it known thatI, REX "IRELAND, a citizen of the United States,residing at Edison, in the county of Morrow and State of Chio, haveinvented a certain new and useful Improvement in Auxiliary SignalDevices, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings.

This invention relates to devices for operating electric bells, and moreparticularly to telephone signal bells having auxiliary signal orextension bells remote from the telephone.

One of the objects is to provide a very simple mechanism connecting anauxiliary bell, or series ofbells, to the operating mechanism of theusual signal bell of a telephone, so that they may be rung whenever theusual or main signal bell isrung.

Another object is to arrange the electric circuits connected to theextension bells so that a separate source of current may be used foroperating them independently of the circuit for the main signal bell ofthe telephone. For example, the main bell may be operated by alternatingcurrent from a magneto and the auxiliary bell by direct current from abattery. rlhis enables easy attachment of the auxiliary bell circuitwithout disturbing the main bell circuits.

Further objects will become apparent in the detailed description of mydevice in connection with the drawings.

In the drawing, Figure 1 is a somewhat diagrammatic view, showing thearrangement ofthe bells and the circuits connecting them; Fig. 2 is aperspective view of the device for operating the `main signal bell, andthe arrangement of the parts for closing the circuit through theauxiliary or extension bell or bells; Fig. 3 is a vertical sectionthrough the operating parts.

Referring to Fig. 1, the numerals 5 and 6 indicate the gongs of theusual signal bell of thetelephone, mounted on the box inclosing themagnet 8 and the device for ringing this bell. 9 indicates the clappercarried on the arm 10, which extends through the side of the box 11 andis carried by the armature 12 of the magnet 8. The magnet 8 may consist`of cores which` are surrounded by coils oppositely wound, and thusadapted to alternately attract the Patented A110'. 18, 1914.

ergized by an alternating current. A usual `source of current for thesemagnets is a magneto generator, indicated at 14, having wires 15 and 16leading to suitable binding posts on the side of the box 11, which areconnected to the magnet 8 by wires 18 and 19. lThis circuit may beopened or closed a suitable switch, indicated at 20.

The parts heretofore described comprise lthc usual means for operating atelephone g bell. My device consists of a mechanism op- ,eratedautomatically by the action of the magnet mentioned for mechanicallyclosing a local circuit through one or more auxiliary y bells, as, forexample, the bell 2l comprises the closing device, to be hereinafterdescribed, and the wires 22 and 23, switch 24,

lwirc 25, bell 21, wire 2G, battery 27 and i wires 28 and 29. The bells21, of which there may be any number, are ofthe ordinary call-bell type,being operated by a direct current :in a local circuit, which isalterends of the pivoted armature 12 when en J nately opened and closed`as the clapper oscillates. Other signals, additional or` substituted,may be operated by this local circuit; for example, an electric light,as indicated at 31.

Referring to Figs. 2 and 3, 30 indicates one side of the box 11 on whichmy device is carried. The magnets` 8l are shown as mounted on a suitablebracket 32 secured to the side 30 of the box l1. The armature 12 has adownwardly projecting wing 4:3 having at: its lower end a gudgeon 33engaging a bracket 35 on the upright bar 3G. A corresponding gudgeon 311projects from the upper edge of the armature 12 and engages theforwardly bent end of the upright bar 36. The armature is thusvertically pivoted and when the magnets 8 are energized it swings onthese pivots, causing the arm 10, which extends through the hole 37, tooscillate to ring the usual bell. The arm 36 is carried by a bracket 38,which is shown as formed of a flat metal strip having a portion 39 bentat right angles thereto and screwed to the side 30 of the box 11. Twoarms 40 and L-l are formed integral with the outer end of the bracket38. Passing through these arms are small screws 42 having conical-shapedpoints which engage suitable recesses in the sidesof the upright bar 36,thus the bar 36 is pivoted on a horizontal axis, and it will be seenthat the armature 12 is pivoted on an axis at substantially right anglesthereto. Secured to the bracket 38 is a metal strip 44 having a portion45 rising diagonally from the bracket, and a portion 47 rising` from thelatter port-ion substantially at right angles to the bracket. A screw48, forming one of the contact members of the local circuit, is threadedthrough this portion 47, and is adapted to abut against a correspondingcontact spring 49 carried by the arm 36, when the armature 12 carriedthereon is drawn toward the magnet 8. Attached to the bracket 38 is thewire 28 forming part of the circuit to the extension bell. The wire 21is connected to the strip 44, which is insulated from the bracket 38,and it will be seen that, when the armature 12 is drawn toward themagnet S, a contact will be made at points of the screws 48 and thespring 49, closing the circuit through the wires which lead to theauxiliary signahthe current passing through the arms 40 and screws 42 tothe bar 36 and thus to the contact spring 49. Between the two arms 49and 41 is a downwardly de pending portion 50 to which is attached asuitable spring 51 adapted to hold the armature normally away from themagnet 8. As shown, this portion 50 has an adjusting screw 52 threadedthrough its lower edge to which is attached the end of the spiraltension spring 51. At its upper end the bar 36 abuts against thedownwardly turned end of a magnet 13 and limits the movement caused bythe spring 51.

The operation of the device is as follows: When the magneto generator 14is operated, the magnet 8 is energized by an alternating current throughthe circuits described and the armature 12 is drawn toward the magnetuntil the spring 49 abuts against the screw 48, by means of the bar 36swinging on its pivot 42 connecting the circuit through the wires 21 and2S and the wires leading to the extension bell or bells. 1While in thisposition, each end of the armature 12 is alternately attracted by eachcoil of the magnet 8 and the arm 10, carrying the clapper 9 is vibrated,thereby giving the usual signal by striking the gongs 5 and 6. Duringthe time the magnets 8 are alternately energized the attraction ofeither magnet for the armature 12 is sufficient to hold the spring 49 inposition to close this circuit. Throughout the time that the magnet 8 isenergized and the clapper 9 thus vibrates back and forth, the localcircuit is continuously connected through the extension bells, which arerung by means of the battery 26 energizing the magnet of each bell.

1t will be seen that any number of extension bells 21 of the ordinaryelectric hell type may be employed, and each of t-hese bells may be rungby means of the battery 27, however remote from the telephone bell. Bythe use of my device, it also becomes possible to use any convenientkbattery 27 g for example, the battery used to ring the door bell mightalso be connected with the extension bell or bells, and used to ringthem.

One of the advantages of my device is that the movable carrier may besubstituted for the present carrier in the ordinary telephone, providinga very convenient method of installing` an auxiliary signal system, andone which may be used for various kinds of electrically-operatedsignals..
